The. result is asshownzin-Fig. 31 zwher-emz the more-or-less spiral turned-over edges atI9 are reinforced, as also are the central rear edges 1 which are toenvelope the hinging portion of the book Adhered to one of theturned-over parts l is a folded page-cover sheet 2| (see adhesive 22).In Fig. '7 this sheet is shown open, its folds 23 and 25 being shown.

The resulting cover with the sheet 2| folded shut is shown in Fig. 3 asbeing applied to a book by turning the cover inside out so that thepockets formed under the pocket flaps I5 are outside and more-or-lessparallel, as shown in Fig. 5. The covers 2! of the book are then alsoturned back approximately parallel and slipped into the pockets underthe pocket flaps [5. Then the covers of the book with the attachedcovering material may be folded along the lines shown in Fig. 6. It willbe noted that the folded sheet 2! ultimately assumes a position at theback of the book where it does not interfere with manipulations of thepages 29.

Whenever it is desired to put the book away for a long period and tohave its pages, as well as its cover, clustproof, the leaves 29 are laidover to the left, front of the book, as shown in Fig. 7. The sheet 2! isthen spread out as shown. In Fig. 7 the sheet 2| is presumed to betransparent, although it may be opaque. Then the leaves 29 are laid overto the right as shown in Fig. 8, and the sheet 2! is folded over fromthe upper and lower sides and then over from the right. The resultingflap 3|, when the book is closed, will be held in position by the frontcover. The book is then completely covered for long storage on a libraryshelf and will be completely protected against dust, mold, insects, etc.If the cover is made opaque, light will also be completely excluded.

In Fig. 9 is shown another form of the invention. In this case, a web 33is employed. The edges in this case are not blanked out. Instead, thereare employed reinforcements 35 which themselves previously have hadtheir edges blanked out to form tongues 31, not unlike the tongues 5.This reinforcing strip is attached by heat sealing or adhesive to theweb the tongues 37 extending. This provides a reinforcement along theedges 39, and also provides the tongues. Then the assembly is cut asalong lines 4| to produce cover blanks as before. Detailed descriptionof the folding of these blanks to produce covers will not be necessarysince they are the same as for the blank shown in Fig. 2. Numerals 38and 40 show the lines upon which this type of blank is folded forproducing the desired cover, adhesive means being used. as before.

In Figs. 10-14 is shown another form of the invention in which a blank43 is produced, having upper and lower tongues 45 and end flaps ll. Inthis case, shorter reinforcements 49 are attached by heat sealing oradhesive. It will be noted that these reinforcements are also arrangedto reinforce along the curve 5| where the tongues fold over into theback of the book. Thus the cover is reinforced at the weakest points.

As indicated by the dotted lines in Fig. 10, the blanks of this form ofthe invention may be made in a series of sizes varying by in.increments. Thus may be accommodated books of various lengths. In orderthat books having various widths of covers and pages may beaccommodated, the lateral length of the blank of Fig. 10 is made longenough to accommodate the largest book width expected within the range.

As indicated in Fig. 11, adhesive is applied to the edges of the flaps41, as indicated at 53. This may be of the kind which is allowed to dryand which is to be reconditioned by wetting, as on an envelope. Theblank is prepared for receiving a book by folding down the tongues 45and attaching bands 55 to the tongues by heat sealing or adhesive. Thesebands 55 are adapted to receive the book covers beneath them. If thecovers of the book are relatively narrow, the conditions shown in Fig.12 will occur, wherein the book covers are shown at 57, its pages beingshown at 59. As described in connection with Fig. 5, the book isinserted with the covers 57 under the strips 55. Then the flaps 41 areturned over as shown at the right in Fig. 12, the adhesive 53 beingwetted and attached to the adjacent bands 55. Heat sealing adhesion mayalso be used. The process is repeated on the left, but in Fig. 12 theleft-hand flap 4? is shown open.

If a book having wider covers is to be accommodated, it is inserted asstated and the flap turned over as indicated, the same being againadhered to the adjacent band 55. In this case, more of each flap 41 willbe left on the outside of the cover, the difference inside being takenup by the width of the corresponding band 55, which is of requisitewidth for the purpose. Thus each cover will accommodate books of avariety of cover and page widths. A limited number of covers, assuggested in Fig. 10, will accommodate themselves to a large range ofbook dimensions.

It should be observed in connection with the disclosure in Figs. 12 and1e that the wrapper 2| has been left off. It is to be understood that ifused it would preferably be attached to the outside of the right-handflap 4? or to the member 55.

An important feature of the invention, among the other mattersdiscussed, is the reinforcement of the hinged portion H of each cover atits upper and, lower ends in the lateral regions between the upper andlower tongues. This is the weakest part of any cover and where tearingusually starts. By means of the present invention, in all forms,reinforcement is provided at these ends of this hinging region H. This,besides making covers of any material stronger, makes pocket type coversof transparent material practicable.

In view of the above, it will be seen that the several objects of theinvention are achieved and other advantageous results attained.

As many changes could be made in the above constructions withoutdeparting from the scope of the invention, it is intended that allmatter contained in the above description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense.

I claim:
